[textile] How can I change the "files" form to truncate the displayed filename?

I’m working on the new Human Resources page on our corp intranet and I’ve had dozens of files submitted by them to be displayed for download on their page. Some of the filenames are quite long (and include an .ext of course) and while I can’t change the name of the actual files I would like to know how I could have them auto-truncated.

HR staff will be uploading/deleting files on their own and I have the following tag on their page.
